Acoustic neuroma is a benign, usually slow-growing tumor derived from the Schwann cells of the vestibulocochlear nerve sheath. The ophthalmic consequence of tumor resection can lead to a multitude of signs and symptoms of neurotrophic keratopathy. The dry exposed anesthetic eye requires long-term ocular lubricants and often an associated surgical procedure(s), usually tarsorrhaphy, to protect the ocular surface. Corneal neurotization has been shown to restore corneal nerve structure and function and improve ocular surface health in recalcitrant cases. This case report presents a delayed but spontaneous recovery of corneal nerve structure and function over 3 years following a surgical resection of an acoustic neuroma.
